In response to arrival of the e-mail from the mobile phone, the data center transfers the image data attached to the e-mail to a database for storing while associating the image data with user ID information for identifying a user who sent the e-mail concerned. Responding to access with ID notification, the data center retrieves designated image data from the database, and transmits the retrieved image data to a photo vending machine. The photo vending machine transmits request information including the user ID information to said data center, and receives the image data which are transmitted by the data center in response to the request information. The photo vending machine prints the arrived image data in accordance with the user&#39;s instruction.

The present application is a Divisional Application of U.S. application Ser. No. 10/602,362 filed Jun. 23, 2003 now U.S. Pat. No. 7,515,289, which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to a network printing system, server, printing machine, and printing method for providing useful printing service for printing image data captured by terminal devices with using a network.

DESCRIPTION OF THE RELATED ART

Photo printing machines for printing photo images captured by a digital still camera have been seen at common places such as shops or streets. Such the printing machines obtain photo images (image data) from the medium inserted thereto, and print the obtained photo images onto predetermined sheets. To use such the printing machine, a user takes out the medium having image data from the digital still camera, and insert it to the printing machine. Once the user select desired images on the printing machine, it prints out the selected images (photo) immediately. Thus, anyone can get photo printing service easily and quickly.

Not only ordinary photo printing, those printing machines also provides additional functions such as superimposing. For example, various frame images or character images are able to be superimposed onto the user's photo images. Those printing machines usually receives the frame image data or character image data via, for example, a communication satellite, and stocks them. In accordance with the user's operation for selecting arbitrary photo images and frame image, the printing machine superimposes the frame image on the selected photo images, and prints them out. Thus, more interesting photo images are available.

Japanese Patent Gazette (Laid Open Application) No. H10-150523 discloses an image storage system for storing photo images on an image server. The image storage system comprises an image server for storing photo images and various devices including a digital still camera. According to the system, various ways are available for transmitting photo images captured by the digital still camera, and various devices are adaptive for accessing the image server to obtain the stored photo images.

Such the conventional printing machines obtain photo images from predetermined removable recording media, thus adaptive devices are limited to predetermined digital still cameras. In other words, some mobile terminals (e.g. mobile phone with camera function) which are not adaptive to a removable recording medium (that is, only internal memory is available) are not adaptive to the conventional printing machines.

Therefore, it has been demanded a new technique for a photo vending machine that is able to obtain photo images from terminal devices without predetermined removable recording media, and provide printing service.

And, there is another demand for more useful optional functions in addition to superimposing frame images or character images on the user's photo.

The relay server 9 relays data communications between the photo vending machine 5 and the data center 4, and between the photo vending machine 5 and the terminal device 2 in accordance with predetermined protocol such as HTTP (Hyper Text Transfer Protocol). More precisely, the relay server 9 receives HTML (Hyper Text Markup Language) files or image files (image data) from the mobile phones 2 a-2 c or the PC 2 d, and transfers them to the data center 4. The relay server 9 also receives image files from the data center 4, and transfers them to the predetermined photo vending machines 5.

Steps and operations for using the network printing system according to the first embodiment will now be described.

User registration is required as a first step for a user who intends to use the system. The user registration is carried out by the network server 3 in response to access by the mobile phone 2 of the user. Operations through the user registration will now be described with reference to FIG. 7 which schematically shows examples of screen images to be displayed on the display unit 26 of the mobile phone 2.

The user inputs URL (Uniform Resource Locator) of the network server 3 to the mobile phone 2. According to the input URL, the mobile phone 4 accesses the web site provided by the network server 3 via the network 1. The network server 3 provides image data of registration form with the mobile phone 2, and the mobile phone 2 displays it by its own web browsing program (Da1). The user fills in the registration form, that is, inputs user's name, address, e-mail address, and password (Da2).

In accordance with the user's operation pointing “OK” button, the mobile phone 2 displays input information for user's review (Da3). If the displayed information is complete, the user may point “OK” button. On the contrary, if any errors are found, the user may point “Back” button for retry.

In response to pointing “OK” button on the review page, the mobile phone 2 transmits the input information to the data center 4. After the data registration on the data center 4 is completed, a message saying “Registration Successful” is displayed on the mobile phone 2 (Da4).

Additionally, in accordance with the user's operation of pointing “Cancel” button during the registration process, the mobile phone 2 may quit the registration.

When the data from the mobile phone 2 arrives at the data center 4, the web server 4 a adds the data to the database 7, thus user information shown in FIG. 4A have been stored in the database 7.

Steps and operations for “Print by Network” provided by the network printing system will now be described with reference to FIG. 8 or other diagrams. FIG. 8 is a schematic diagram for explaining consecutive operations in the “Print-by-Network”. Through the “Print by Network”, image data IM in the mobile phone 2 is forwarded to the data center 4 by e-mail Ma1 to be registered to the database 7, and the photo vending machine 5 prints out the registered image data IM.

More precisely, the mobile phone 2 activates its e-mail transmission function to transmit e-mail Ma1 to which the image file (image data IM) is attached, to the data center 4. The transmission action will now be described with reference to FIG. 9. FIG. 9 is a diagram schematically showing screen images displayed on the display unit 26 of the mobile phone 2.

The user may capture images by the built-in camera of the mobile phone 2. The captured images are stored in the internal memory or the like as photo image (image data). In accordance with the user's operation, the mobile phone 2 displays the image data to be printed (Db1).

In accordance with the user's operation pointing “e-mail” button, the mobile phone 2 displays empty e-mail to be filled in by the user. Articles on the empty e-mail are “To” (addressee), “Subject”, and “Message” (Db2). “To” is prepared for inputting addressee's e-mail address, and “Subject” is prepared for inputting file name of the image file to be transmitted. Additionally, “Message” may be filled in by information representing, for example, date of image data generation, comments, and the like. After the e-mail transmission has been ready, the user operates “Send” button, thus instruction for transmitting e-mail is given to the mobile phone 2.

In response to the “Send” button operation, the mobile phone 2 transmits the e-mail Mat to which the image data to be printed is attached, to the data center 4. After the transmission is successful, the mobile phone 2 displays a message saying that the transmission has been completed (Db3).

The above e-mail transmission may be canceled in accordance with the user's operation pointing “Cancel” button.

The data center 4 receives the e-mail Ma1 to which the image file(s) are attached, from the mobile phone 2 (FIG. 8). The data center 4 receives various e-mails through “E-mail Receiving Process” shown in FIG. 10.

The e-mail receiving process will now be described with reference to FIG. 10. As shown in FIG. 10, the e-mail server 4 c has been in a standby mode for receiving e-mails from the mobile phones 2 (S1). Once an e-mail arrives, the e-mail server 4 c determines the e-mail has attached file or not (S2).

If no files is found, the e-mail server 4 transfers message in the e-mail to a memory or the like (not shown), and deletes the e-mail (S3). And the process flow returns to S1.

On the contrary, if any file is attached to the e-mail, the e-mail server 4 c determines whether the attached file is image file (image data) or not (S4).

If it is not an image file, the e-mail server 4 c carries out the process at S3. On the other hand, if the e-mail has an attached image file, the web server 4 a stores the file on the database 7 (S5). Predetermined numbering operation is carried out during the image file storing, thus unique image ID is given. And thus numbered image files are stored in predetermined areas in the print image information shown in FIG. 4B being linked to the user information.

For example, if a user whose user code is “200201290001” transmits an image file, the web server 4 a designates area 7 a having link code “001” as a recording area for the image file. If the sender of the image file is a user whose user code is “200201290002”, the web server 4 a stores the image data in the area 7 b to which link code “002” is assigned.

In a case where a plurality of image files are attached to an e-mail, or a plurality of e-mails are transmitted by the same user, the web server 4 a those image files in the same area corresponding to the user code concerned.

After the image data are stored in the database 7 by the web server 4 a, the e-mail server 4 c carries out “Notice Transmission Process” for transmitting a notice to the sender of the image file by e-mail as shown in FIG. 10 (S6).

The notice transmission process will now be described with reference to FIG. 11. As shown in FIG. 11, the e-mail server 4 c prepares a notice document based on a configuration file in which contents of the notice are defined (S6-1). The notice may have a message saying that, for example, the image data registration has been completed.

Then, the e-mail server 4 c determines whether the e-mail address of the e-mail Ma1 is unregistered one or not (S6-2). In other words, the e-mail server 4 c determines whether the e-mail Ma1 was sent by the user who has been registered in the database 7 (user information shown in FIG. 4A) or not.

If it is determined that the e-mail Ma1 was sent by registered user (not unregistered), the e-mail server 4 c obtains corresponding user ID (user code) from the user information (S6-3).

On the contrary, if it is determined that the sender's e-mail address of the e-mail address Ma1 is unregistered, the e-mail server prepare unique user ID and password, and adds them to the database 7 to save (S6-4). The password may be prepared automatically in accordance with a predetermined rule.

The e-mail server 4 c obtains image ID assigned to the image file which was registered at S5 (see E-mail Receiving Process shown in FIG. 10) (S6-5).

Then the e-mail server 4 c transmits an e-mail Ma2 including the prepared notice document to the mobile phone 2 which sent the e-mail Ma1 (S6-6). In a case where the user ID and password were prepared at S6-4, the notice document in the e-mail Ma2 includes the user ID and password.

Thus transmitted e-mail Ma2 is forwarded to the mobile phone 2 as shown in FIG. 8. In response to arrival of the e-mail Ma2, the mobile phone 2 displays the contents of the e-mail Ma2. According to this action, the user is notified that the image data has been registered to the data center 4 successfully. User ID and password are also notified to a user who has just registered.

Once the image files are registered to the data center 4, the user is able to browse the images through his/her own mobile phone 2. This browsing process will now be described with reference to FIG. 12. FIG. 12 is a diagram schematically showing screen images displayed on the mobile phone 2.

According to the user's operation, the mobile phone 2 accesses the data center 4, and displays a login page through the browser program (Dc1). Then, the mobile phone 2 transmits password input by the user and its e-mail address to the data center 4.

In response to the reception of the password and e-mail address from the mobile phone 2, the data center 4 accesses the database 7, and searches for the registered image data based on the password and e-mail address. The data center 4 creates preview images of the registered image data (e.g. thumbnail images), and transmits them to the mobile phone 2.

In response to the reception of preview image data, the mobile phone 2 displays the preview images (thumbnail images) (Dc2). If a user selects one of the thumbnail images, the mobile phone 2 requests the data center 4 to transmit original image, thus the mobile phone 2 displays the original images in accordance with the user's selection (Dc3). Additionally, the user's operation of pointing “Next” button also causes the request, thus the following original images are displayed in accordance with the user's operation (Dc4).

The photo vending machine 5 carries out “Printing Process” shown in FIG. 13 to print arbitrary image data registered in the data center 4 in accordance with the user's operation as shown in FIG. 8.

“Printing Process” will now be described in detail with reference to FIG. 13. As shown in FIG. 13, the system is initialized, and the photo vending machine 5 stands by user's operations (ST1).

If it is detected that a memory card (recording medium on which image data are recorded) is inserted to the photo vending machine 5 (ST2), the process at ST8 (described later) is carried out. On the contrary, if it is detected that no memory card is inserted, the photo vending machine 5 detects whether “Print by Network” is selected or not (ST3).

If the “Print by Network” is not selected, the photo vending machine 5 carries out the process at ST2. On the contrary, the photo vending machine requires a user to input user ID and password when “Print by Network” is selected (ST4). In this case, the photo vending machine 5 displays the login page as shown in FIG. 14A to obtain user ID (user code) and password. The photo vending machine 5 transmits the obtained user ID and password to the data center 4, and requests user authentication.

The photo vending machine 5 determines whether the user authentication was successful or not (ST5). If it is determined that the user authentication was not successful, the photo vending machine 5 determines whether the operation has been canceled or not (ST6). If the operation is canceled, the photo vending machine 5 carries out the step at ST2. On the other hand, if the operation has not been canceled, the photo vending machine 5 requires the user to retry (ST7), and carries out the process at ST4 again.

During the above steps, the data center 4 carries out the following operations. That is, the data center 4 retrieves registered image data from the database 7 if the user authentication has been successful. More precisely, the data center 4 retrieves image data in an area corresponding to the user code of the authenticated user based on the print image information shown in FIG. 4B.

For example, if the user code concerned is “200201290001”, the data center 4 retrieves image data from the area 7A whose link code is “001”. In a case where the user code is “2002012902”, the data center 4 selects the area 7 b to which link code “002” is assigned and retrieves image data from there.

In case of successful user authentication at ST5, the photo vending machine 5 displays image data and stands by for user's image selection (ST8).

For example, the photo vending machine 5 receives the image files which were retrieved from the database 7 by the data center 4, and displays the images as shown in FIG. 14B. The user operates cursor keys or the like to select desired image to be printed from the displayed images, and operates “Print” button as shown in FIG. 14C, thus instruction for printing is given to the mobile phone 2.

In a case where the insertion of the memory card has been recognized at ST2, the photo vending machine 5 displays images represented by the image data retrieved from the memory card, and accepts the user's selection of the images.

When an instruction for printing is given by the user after the image selection, the charging unit 54 of the photo vending machine 5 calculates fee (ST9), and waits for payment (ST10 and ST11). Any events related to canceling is given (e.g. user's instruction, time out, or the like), the photo vending machine 5 carries out the process at ST2.

If it is determined that the fee is paid, executes the operation for printing the selected image data (ST12). That is, the photo vending machine 5 prints out the selected image data onto the predetermined sheets. If any layout instruction has been given, the photo vending machine 5 prints the image data in accordance with the layout instruction.

For example, if an instruction of “4-in-1” layout (combining 4 images on 1 sheet) is given, 4 images are printed on a sheet as shown in FIG. 15A. In the same manner, “12-in-1” layout instruction leads the printing as shown in FIG. 15B. The printed sheet is discharged through an outlet.

After the printing is completed, the photo vending machine 5 issues a receipt (ST13, FIG. 13). Then, the process at ST2 is carried out again.

According to the above described network printing system of the first embodiment, printing of images captured by a mobile phone 2 having camera function is available with using the network without using any memory cards. That is, the photo printing service is available for users who use the devices not adaptive to removable recording media.

Though the mobile phones having camera function have been exemplified as terminal devices 2 in the first embodiment, devices being able to enjoy the effect of the resent invention are not limited to them. For example, the PC 2 d or a PDA having camera function also enjoy the effect of the present invention. For example, a wrist watch having camera function is also available one. In this case, such the wrist watch is able to work as the terminal device 2, after installation of application programs which brings the above described functions such as the user registration, e-mail transmission, image browsing. Those application programs may be downloadable from the network server 3.

In case of the memory card insertion, the photo vending machine 5 obtains image data from the memory card, and displays them for accepting the user's selection (W3). Then the process flow skips to W24 (described later).

If the memory card insertion is not recognized, the photo vending machine 5 detects whether “Print by Network” is selected by the user (W4). Unless the “Print by Network” is selected, the process flow returns to W2.

In case of “Print by Network”, the photo vending machine 5 accepts the user's operation for inputting e-mail address (W5). In this case, the photo vending machine 5 displays a predetermined input form, and obtains e-mail address of the user's mobile phone 2.

Then, the photo vending machine 5 prepares server URL which indicates the data server 4 assigned for the photo vending machine 5 concerned (W6). In a case where the server URL of the photo vending machines 5 a and 5 b are set as shown in FIG. 22B, the photo vending machine 5 a prepares “www.***.jp/001,” as the server URL. In the same manner, the photo vending machine 5 b prepares “www.***.jp/002” as the server URL. If script style as shown in FIG. 22C is available, the photo vending machines 5 may prepare the server URL as shown in FIG. 22C, instead of those shown in FIG. 22B.

As shown in FIG. 23, the photo vending machine 5 prepares an e-mail including the prepared server URL, and transmits it to the mobile phone 2 (W7).

After the e-mail transmission is completed, the photo vending machine 5 accesses the data server 4 (W8) to determine whether thumbnail images from the mobile phone 2 are stored in the data server 4 (W9). Simultaneously, the photo vending machine 5 detects whether timed out or not (W10). If it is detected that timed out, the process flow returns to W2.

In response to reception of the e-mail from the photo vending machine 5, the mobile phone 2 activates the Java application program, and the image data transmission process shown in FIG. 24 automatically starts.

As shown in FIG. 24, the mobile phone 2 receives the e-mail from the photo vending machine 5 (W11), and determines whether it includes server URL or not (W12).

In case of no server URL, the mobile phone 2 displays a predetermined input form for accepting the user's manual input (W13).

The mobile phone 2 accesses the data server 4 in accordance with the server URL (W14). In a case where time-out occurs or the connection is failed because of incorrect URL, the process is canceled.

After the connection is established, the mobile phone 2 automatically transmits thumbnail image data representing the stored images to the data server 4 (W15), until transmission of all thumbnail images is completed (W16).

After the thumbnail image data transmission, the mobile phone 2 waits for a print list given by the photo vending machine 5 (W17), while detecting whether timed out or not (W18). If it is timed out at W18, the image data transmission process is canceled.

The data server 4 receives the thumbnail image data from the mobile phone 2, and stores the thumbnail image data in a designated directory.

After the thumbnail image data saving at W9, the photo vending machine 5 duplicates the thumbnail image data (W21), until duplication of all thumbnail images is completed (W22).

After the duplication of the thumbnail image data, the photo vending machine 5 displays thumbnail images represented by the duplicated thumbnail image data, to accept the user's operation for selecting desired images (W23).

In response to the user's instruction for printing after selecting the images, the photo vending machine 5 calculates fee (W24) and waits for payment (W25, W26). Any events for canceling occurs at W26, the process flow returns to W2.

If the payment at W25 is sufficient, the photo vending machine 5 generates a print list which indicates the selected images, and transmits it to the data server 4 (W27).

After transmitting the selection list, the photo vending machine 5 waits for image data given by the mobile phone 2 (W28), while detecting whether timed out or not (W29). If it is timed out at W29, the process flow returns to W2.

In response to reception of the print list from the photo vending machine 5, the data server 4 carries out “Responding Process” (described later) to store the print list.

The mobile phone 2 receives the print list from the photo vending machine 5 and stores it at W17 (FIG. 24), and refers to the print file to recognize the total number of images (W31). The mobile phone 2 further obtains file names (titles) from the print list for identifying the image data (W32). Those file names are set to a predetermined management table.

The mobile phone 2 transmits image data to be printed to the data server 4 in accordance with the management table. More precisely, the mobile phone 2 initializes file No. pointer (which points file No. of the files in the management table) to “0” (W33), and specifies image data corresponding to file name corresponding to present file No. pointed by the pointer. The mobile phone 2 transmits the specified image data to the data server 4 (W34).

After one image file is transmitted, the mobile phone 2 updates “completion counter” (W35), and determines whether the completion counter is equal to or greater than the total number of the files (W36). In other words, the mobile phone 2 determines whether all image data to be printed have been transmitted completely or not.

If the transmission of all image data has not been completed, the mobile phone 2 updates the pointer to increment file No. +1 (W37), and the process flow returns to W34. After the all image data have been transmitted completely, the mobile phone 2 disconnects the data server 4 (W38), and terminates the image data transmission process.

The data server 4 receives the image data from the mobile phone 2, and stores them in accordance with the responding process (described later).

As shown in FIG. 23, the photo vending machine 5 carries out duplication of the image data stored at W28 (W41), until all image data are duplicated (W42).

After the image data duplication, the photo vending machine 5 execute printing process for printing the duplicated image data (W43). More precisely, the photo vending machine 5 prints out the image data selected by the user, and outputs the photo prints. If any layout instruction has been given, the photo vending machine 5 prints a plurality of images on one sheet as shown in FIG. 15A or 15B.

In response to completion of the printing, the photo vending machine 5 instructs the data server 4 to delete the data stored therein (W44), and disconnect the data server 4 (W45). Then, the photo vending machine 5 issues a receipt (W46), and the process flow returns to W2.

The responding process carried out by the data server 4 which intermediates the data transfer between the photo vending machine 5 and the mobile phone 2 will now be described with reference to FIG. 25.

As shown in FIG. 25, the data server 4 initializes the system (SW-1), and stand by for accesses (SW-2).

In response to access from the mobile phone 2, the data server 4 determines whether directory (directory name) is designated or not (SW-3). If designation is not recognized, the process flow skips to SW-7 (described later). If directory name is designated, the data server 4 determines whether a directory having the designated name exists or not (SW-4). If such the directory has not existed, the data server 4 prepares a directory with affixing the name designated (SW-5).

The data server 4 designates the directory concerned as a current directory (SW-6).

The data server 4 determines whether the thumbnail image data have arrived from the mobile phone 2 or not (SW-7). Only when the thumbnail image data are received, the data server 4 stores the thumbnail image data in the current directory (SW-8).

The data server 4 further determines whether the print list has arrived from the photo vending machine 5 or not (SW-9). Only when the print list is received, the data server 4 stores the print list in the current directory (SW-10).

The data server 4 further determines whether image data have arrived from the mobile phone 2 or not (SW-11). In response to the reception, the data server 4 stores the image data on the current directory (SW-12).

Then the data server 4 determines whether the mobile phone 2 has been disconnected from the data server 4 or not (SW-13). If the mobile phone 2 has not been disconnected, the process flow returns to SW-3. On the contrary, the process flow returns to SW-2 when the disconnection is detected.

According to the network printing system of the fourth embodiment, printing of images captured by the mobile phone 2 having the camera function is available with using the network. In this case, since thumbnail image data or image data are automatically transmitted to the data server 4 from the mobile phone 2, the printing service is available even if the user does not have the terminal device with him/her.

Though, the fourth embodiment above exemplifies a case where the image data are transferred to the photo vending machine 5 after those are transferred to the data server 4 once, the mobile phone 2 may transmits the image data and the like to the photo vending machine 5 directly.

Instead of the mobile phones 2 (2 a, 2 b, and 2 c), the PC 2 d or the PDA having camera function is also applicable one as the terminal device 2. Moreover, a wrist watch having camera function is also applicable. In this case, even if Java application software which realizes the above described image data transmission process is installed in the wrist watch, it works as the terminal device 2 as well as the mobile phone 2 exemplified in the fourth embodiment. Those Java application software may be downloadable from, for example, the network server 3.

Fifth Embodiment

A network printing system according to a fifth embodiment of the present invention will now be described.

The network printing system of this embodiment also realizes the automatic data transfer before printing, as well as the fourth embodiment. In addition, date indication is available.

Hardware components of the printing system according to the fifth embodiment are the same as those of the system in the first embodiment shown in FIG. 1. As well as the second embodiment, the terminal devices 2 are adaptive to the Java applications. That is, the mobile phones 2 a, 2 b, and 2 c have the same structures as those described in the second embodiment.

Operations of thus structured network printing system of the fifth embodiment will now be described.

The photo vending machine 5 executes the printing process shown in FIG. 26, while the mobile phone 2 carries out the image data transmission process shown in FIG. 27 (automatic transmission process shown in FIG. 28).

As shown in FIG. 26, the photo vending machine 5 initializes the system (V1), and detects whether the memory card is inserted or not (V2).

In case of the memory card insertion, the photo mending machine 5 obtains image data from the memory card, and stands by for the user's image selection (V3). Then, the process flow skips to V27 (described later).

In a case where no memory card is recognized, the photo vending machine 5 determines whether “Print by Network” is selected by the user or not (V4).

In case of “Print by Network”, the photo vending machine 5 accepts the user's operation for inputting e-mail address (V5).

The photo vending machine 5 also accepts information representing month or date on which the images are captured (V6). Those information will be used for designating the image data. For example, the photo vending machine 5 obtains “2003/01” or “2003/02” (Year and Month) as month information, or “2003/02/20” or “2003/02/21” (Year, Month, Date) as the date information. The photo vending machine 5 generates date information based on those obtained information.

Once the assigned server URL is prepared (V7), the photo vending machine 5 adds the date information to the server URL. The photo vending machine 5 prepares an e-mail including the server URL, and transmits it to the mobile phone 2 (V8).

For example, if “2003/02/20” and “2003/02/21” are designated as date information, the server URL information includes the date information as shown in FIG. 29A. In a case where “2003/01” and “2003/02” are designated as month information, the server URL information includes the date information as shown in FIG. 29B. Or, if “2003/01” is designated as month information while “2003/02/20” is designated as date information, the server URL information includes the date information as shown in FIG. 29C. The photo vending machine 5 transmits an e-mail including such the exemplified server URL information.

After the e-mail transmission at V8 (FIG. 26), the photo vending machine 5 accesses the network server 3 (V9), and waits for arrival of the thumbnail image data from the mobile phone 2 (V10) while detecting whether timed out or not (V11). If is detected that it is timed out, the process flow returns to V2.

In response to arrival of the e-mail from the photo vending machine 5, the mobile phone 2 activates the Java application software to execute the image data transmission process shown in FIG. 27 automatically.

As shown in FIG. 27, the mobile phone 2 receives the e-mail from the photo vending machine 5 (V12), and determines whether the e-mail includes the server URL information or not (V13). In case of no server URL information, the mobile phone 2 accepts the user's manual input to obtain the server URL (V14).

The mobile phone 2 further determines whether the date information is added to the server URL information or not (V15). In case of no date information, the mobile phone 2 accepts the user's manual input in order to obtain the date information (V16).

The mobile phone 2 sets up the date search based on the date information (V17), and accesses the data center 4 in accordance with the given server URL (V18). In case of canceling or connection failure caused by incorrect URL, the image data transmission process may be canceled.

In response to establishment of the connection to the data center 4, the mobile phone 2 searches for image data corresponding to designated date (V19), and automatically transmits thumbnail image data representing found image data (V20). The thumbnail image data transmission is continued until it is determined that the thumbnail image data representing all of the found images is transmitted completely (V21).

After the transmission of the thumbnail image data, the mobile phone 2 waits for arrival of the print list given by the photo vending machine 5 (V22) while detecting whether timed out or not (V23). If time-out is detected, the mobile phone 2 may cancel the image data transmission process.

In response to reception of the thumbnail image data from the mobile phone 2, the data center 4 transfers the thumbnail image data to the designated directory for storing.

After the thumbnail image data storing at V10 (FIG. 26), the photo vending machine 5 duplicates the thumbnail image data (V24). The duplication is continued until it is determined that all thumbnail image data are duplicated (V25).

Following to the thumbnail image data duplication, the photo vending machine 5 displays thumbnail images in accordance with the thumbnail image data in order to accept the user's operation for selecting images (V26).

In accordance with the user's instruction for printing after arbitrary images are selected, the photo vending machine 5 calculates fee (V27), and waits for payment (V28, V29). If any canceling event occurs, the process flow returns to V2.

When payment is recognized at V28, the photo vending machine 5 prepares a print list indicating the selected images, and transmits it to the data center 4 (V30).

After the print list transmission, the photo vending machine 5 waits for the image data transferred from the mobile phone 2 (V31), while detecting timed out or not (V32). If time-out is detected, the process flow returns to V2.

In response to arrival of the print list from the photo vending machine 5, the data center 4 stores the print list.

After the print list is stored at V22 (FIG. 27), the mobile phone 2 refers to the print list to recognize the total number of the image files (V33). Further, the mobile phone 2 obtains file name information or the like from the print list in order to identifies the image data. Those information are set to a predetermined management table (V34).

The mobile phone 2 carries out the automatic transmission process in accordance with the contents of the management table (V35). The process will now be described with reference to FIG. 28.

As shown in FIG. 28, the mobile phone 2 initializes file No. pointer to “0” (V35-1). The file No. pointer indicates file No. of the files in the management table. The mobile phone 2 opens the image data having the file name corresponding to file No. pointed by the pointer (V35-2).

The mobile phone 2 transfers header information included in the image data concerned to the predetermined memory (V35-3), and determines whether date information is available in the header information or not (V35-4).

In a case where the date information is not available, the mobile phone 2 adds information representing “no date information” to the header information (V35-5).

Then the mobile phone 2 creates matching data of the date and file names (V35-6), and transmits image data to the data center 4 (V35-7).

After the image data transmission, the mobile phone 2 closes the image data corresponding to file No. pointed by the pointer (V35-8), and updates completion counter (V35-9). The mobile phone 2 determines whether the completion counter value becomes equal to or greater than the total file numbers or not (V35-10). That is, it is determined whether all image data to be printed are completely transmitted or not.

If the transmission of all image data has not been completed, the mobile phone 2 updates the pointer to increment file No. +1 (V35-11), and the process flow returns to V35-2.

In response to completion of the image data transmission, the automatic data transmission process is terminated, and the process flow returns to the image transmission process shown in FIG. 27.

After the completion of the automatic process, the mobile terminal 2 disconnects the data center 4 (V36), thus the image data transmission process is terminated.

In response to arrival of the image data from the mobile phone 2, the data center 4 stores the arrived image data.

Following to the image data storing at V31 (FIG. 26), the photo vending machine 5 duplicates the image data (V37). The duplication is continued until all image data are completely duplicated (V38).

After the duplication, the photo vending machine 5 prints the duplicated image data (V39). More precisely, the photo vending machine 5 prints out the image data corresponding to the date designated by the user, and outputs the photo print.

In response to completion of the printing, the photo vending machine 5 instructs the data center 4 to delete the image data (V40), and disconnects from the data center 4 (V41). Finally, the photo vending machine 5 issues a receipt (V42), and the process flow returns to V2.

According to the network printing system of the fifth embodiment, printing service for printing images captured by the mobile phone 2 having the camera function is available with using the network. In this case, since the thumbnail image data including designated date information or the image data are automatically transmitted to the photo vending machine 5 from the mobile phone 2, the users are released from operations. Moreover, the printing service is available even if the terminal device is not held by the user.

Though, the fifth embodiment above exemplifies a case where the image data are transferred to the photo vending machine 5 after those are transferred to the data center 4 once, the mobile phone 2 may transmits the image data and the like to the photo vending machine 5 directly.

Instead of the mobile phones 2 (2 a, 2 b, and 2 c), the PC 2 d or the PDA having camera function is also applicable one as the terminal device 2. Moreover, a wrist watch having camera function is also applicable. In this case, even if Java application software which realizes the above described image data transmission process is installed in the wrist watch, it works as the terminal device 2 as well as the mobile phone 2 exemplified in the fifth embodiment. Those Java application software may be downloadable from, for example, the network server 3.

Sixth Embodiment

A network printing system according to a sixth embodiment will now be described.

The network printing system of this embodiment is similar to that of the fourth embodiment, however, thumbnail image data transfer is omitted.

Hardware components of the network printing system according to the sixth embodiment are the same as those of the system according to the first embodiment shown in FIG. 1. As well as the second embodiment, the terminal devices 2 are adaptive to the Java application software. That is, the mobile phones 2 a, 2 b and 2 c have the same structure as the structure of the mobile phones 2 according to the second embodiment.

Operations through using the system according to the sixth embodiment will now be described.

The photo vending machine 5 carries out the printing process shown in FIG. 30, while the mobile phone 2 carries out the image data transmission process shown in FIG. 31.

As shown in FIG. 30, the photo vending machine 5 initializes the system (U1), and detects whether a memory card is inserted or not (U2).

In case of the memory card insertion, the photo vending machine 5 obtains image data from the memory card, and displays the images in order to accept the user's operation or selecting images (U3). Then, the process flow skips to U24.

In a case where the memory card has not been recognized, the photo vending machine 5 determines whether the user selects “Print by Network” or not (U4).

If “Print by Network” is not selected, the process flow returns to U2. On the contrary, the photo vending machine 5 accepts the user's operation for inputting e-mail address of the user's mobile phone 2, if “Print by Network” has been selected (U5).

The photo vending machine 5 prepares server URL information assigned to the photo vending machine 5 concerned (U6), and transmits an e-mail including the server URL information to the mobile phone 2 (U7).

After the e-mail transmission, the photo vending machine 5 accesses the data center 4 (U8), and waits for arrival of the image data from the mobile phone 2 (U9), while detecting timed out or not (U10). If time-out is detected, the process flow returns to U2.

In response to reception of the e-mail from the photo vending machine 5, the mobile phone 2 activates the Java application program, thus the image data transmission process shown in FIG. 31 is automatically executed.

More precisely, the mobile phone 2 receives the e-mail from the photo vending machine 5 (U11), and determines whether the e-mail includes the server URL information or not (U12).

In case of no server URL information, the mobile phone 2 may display input form to accept the user's manual input of the server URL (U13).

Then, the mobile phone 2 accesses the data center 4 in accordance with the server URL concerned (U14). The image data transmission may be cancelled, if any cancel events such as time-out and connection failure caused by incorrect URL.

After the connection is established, the mobile phone 2 displays the images represented by the stored image data, in order to accept the user's operation for selecting the images (U15). The mobile phone 2 transmits the image data of the selected images to the data center 4 (U16). The image data transmission is continued until the user's image selection is completed (U17).

In response to the completion of the image selecting, the mobile phone 2 disconnects from the data center 4 (U18), thus the image data transmission process is terminated.

When the image data are transferred from the mobile phone 2 to the data center 4, the data center 4 carries out the responding process (described later) to store the image data in the designated directory.

In response to the image data storing at U9 (FIG. 30), the photo vending machine 5 duplicates the image data (U21). The duplication is continued until all image data are duplicated completely (U22).

After the image data duplication, the photo vending machine 5 displays the duplicated image data in order to accept the user's operation for selecting the images (U23).

In response to the user's instruction for printing after selecting desired images to be printed, the photo vending machine 5 calculates fee (U24), and waits for payment (U25, U26). If any cancel event occurs at U25, the process flow returns to U2.

When the payment is recognized, the photo vending machine 5 executes the printing (U27). That is, the photo vending machine 5 prints out the selected image data on a predetermined sheet, and outputs the photo print.

After the printing, the photo vending machine 5 instructs the data center to delete the image data therein (U28), and disconnects from the data center 4 (U29). Finally, the photo vending machine issues a receipt (U30), and the process flow returns to U2.

The responding process carried out by the data center 4 will now be described with reference to FIG. 32. The data center 4 intermediates the data transfer between the photo vending machine 5 and the mobile phone 2.

As shown in FIG. 32, the data center 4 initializes the system (U18-1), and waits for access (U18-2).

If the data center 4 is accessed by the mobile phone 2, the data center 4 determines whether a directory is designated or not (U18-3). In case of no designation of directory, the process flow skips to U18-7 (described later). If any directory is designated, the data center 4 confirms whether the designated directory exists or not (U18-4). The data center 4 creates a directory only when the designated directory has not existed (U18-5).

The data center 4 sets the directory concerned as a current directory (U18-6).

The data center 4 determines whether the image data from the mobile phone 2 arrived or not (U18-7), and stores the image data in the current directory only when the image data arrived (U18-8).

Further, the data center 4 determines whether the connection has been maintained or not (U18-9). If the connection has been maintained, the process flow returns to V18-3, while the process flow returns to U18-2 in case of disconnection.

According to the network printing system of the sixth embodiment, printing service for printing images captured by the mobile phone 2 with camera function is available with using the network.

Though, the sixth embodiment above exemplifies a case where the image data are transferred to the photo vending machine 5 after those are transferred to the data center 4 once, the mobile phone 2 may transmits the image data and the like to the photo vending machine 5 directly.

Instead of the mobile phones 2 (2 a, 2 b, and 2 c), the PC 2 d or the PDA having camera function is also applicable one as the terminal device 2. Moreover, a wrist watch having camera function is also applicable. In this case, even if Java application software which realizes the above described image data transmission process is installed in the wrist watch, it works as the terminal device 2 as well as the mobile phone 2 exemplified in the sixth embodiment. Those Java application software may be downloadable from, for example, the network server 3.

Seventh Embodiment

A network printing system according to a seventh embodiment of the present invention will now be described.

The network printing system of this embodiment employs DPOF (Digital Print Order Format) for designating images to be printed or the number of print copies. More precisely, the image data recorded in the terminal device 2 are transferred to the photo vending machine 5 in accordance with DPOF. The photo vending machine 5 prints thus transferred image data.

Hardware components of the network printing system according to the seventh embodiment are the same as those of the system according to the first embodiment shown in FIG. 1. As well as the second embodiment, the terminal devices 2 are adaptive to the Java application software. That is, the mobile phones 2 a, 2 b and 2 c have the same structure as the structure of the mobile phones 2 according to the second embodiment.

Operations through using the network printing system according to the seventh embodiment will now be described. For comprehensive explanation, the following description will refer to FIG. 33A which is a simplified diagram showing the whole configuration of the network printing system. FIGS. 33B and 33C are diagrams each exemplifying configuration data representing server URL assigned to the photo vending machines 5 (5 a, 5 b) respectively. Designation information according to DPOF is affixed to the server URL information.

Under such the configuration, the photo vending machine 5 executes the printing process shown in FIG. 34, while the mobile phone 2 carries out the image data transmission process shown in FIG. 35.

As shown in FIG. 34, the photo vending machine 5 initializes the system (Y1), and detects whether the user inserts a memory card or not (Y2).

In case of using the memory card, the photo vending machine 5 obtains image data from the memory card, and displays the images corresponding to the image data in order to accept the user's operation for selecting the images (Y3). In this case, the process flow skips to Y40 (described later).

If the memory card is not recognized, the photo vending machine 5 determines whether “Print by Network” is selected by the user or not (Y4).

If “Print by Network,” is not selected, the process flow returns to Y2, while accepting the user's input of e-mail address when “Print by Network” is selected (Y5).

The photo vending machine 5 prepares server URL information representing server URL assigned to the photo vending machine 5 concerned (Y6). The photo vending machine 5 further affixes designation information of DPOF to the prepared server URL information. Examples of the server URL information to which the DPOF designation information is affixed are shown in FIGS. 33B and 33C.

Then, the photo vending machine 5 generates an e-mail including the server URL information to which the DPOF designation information is affixed, and transmits it to the mobile phone 2 (Y7).

After the e-mail transmission, the photo vending machine 5 accesses the data server 4 (Y8).

In response to arrival of the e-mail from the photo vending machine 5, the mobile phone 2 activates the Java application program, thus the image data transmission process shown in FIG. 35 is executed automatically.

As shown in FIG. 35, the mobile phone 2 receives the e-mail from the photo vending machine 5 (Y11), and determines whether the e-mail includes the server URL information or not (Y12). In case of no URI inclusion, the mobile phone 2 obtains it by the user's input (Y13).

The mobile phone 2 further determines whether the DPOF designation information is affixed to the server URI, information (Y14). In case of no DPOF information, the mobile phone 2 obtains the same by the user's input (Y15). Then, the mobile phone 2 adds a DPOF parameter to the server URL information (Y16). For example, when the DPOF designation information indicates “/001/index.php&dpof=1”, the mobile phone 2 adds “$dpof==‘1’” to the server URL information as the parameter.

The mobile phone 2 recognize the directories in its memory card (Y17), and obtains the DPOF file (Y18). For example, the mobile phone 2 (mobile phone 2 a) recognizes directory configuration 2 ad in the memory card as shown in FIG. 33A, and obtains the DPOF file “AUTOPRINT.MRK” from the directory “./MISC/”.

In the “./MISC/” directory, files for automatic printing, automatic data transmission, automatic image display, and the like. Those files are components of the DPOF file.

The mobile phone 2 accesses the data server 4 in accordance with the server URL information (Y19). The image data transmission process may be canceled by time-out or access failure caused by incorrect URL.

After the connection is established, the mobile phone 2 transmits directory name information representing name of the directory where the DPOF file is stored (Y20). For example, in a case where the mobile phone 2 recognizes the directory configuration 2 ad shown in FIG. 33A, information representing the directory name “./MISK/” is transmitted to the data server 4. Following to this action, the mobile phone 2 transmits the DPOF file to the data server 4 (Y21). In this case, the mobile phone 2 transmits the DPOF file “AUTOPRINT.MRK” in case of the directory configuration 2 ad.

Further, the mobile phone 2 transmits information representing name of the directory storing the image data, to the data server 4 (Y22). In case of the directory configuration 2 ad, for example, the mobile phone 2 transmits information representing “./DCIM” which is the name of the directory storing the image data. Then, the mobile phone 2 transmits the image data designated by the DPOF file to the data server 4 (Y23). In a case where, for example, the directory configuration 2 ad has been recognized while “AAA.JPG” and “BBB.JPG” are designated by “AUTOPRINT.MRK” as the image data to be printed, the mobile phone 2 transmits the image data “AAA.JPG” and “BBB.JPG” sequentially. Such the data transmission is continued until all image data designated by the DPOF file are transmitted completely (Y24).

In response to the completion of the data transmission, the mobile phone 2 disconnects from the data server 4 (Y25), thus the image data transmission process is terminated.

The data server 4 carries out the responding process (described later) to prepare directory, and stores the DPOF file or the image files in the directory concerned. For example, the data server 4 duplicates the directory configuration 4 d shown in FIG. 33A in accordance with the directory name information, the DPOF file, and the image file sent by the mobile phone 2.

The photo vending machine 5 which has accessed the data server 4 at Y8 (FIG. 34), waits for storing of the DPOF file (Y31). When the DPOF file is stored in the data server 4, the photo vending machine 5 duplicates the directory of the DPOF file (Y32), and duplicates the DPOF file into the duplicated directory (Y33).

The photo vending machine 5 further waits for storing the image data (Y34) while detecting whether timed out or not (Y35). In case of time-out, the process flow returns to Y2.

After the image data are stored in the data server 4, the photo vending machine 5 duplicates the directory of the image data (Y36), and duplicates the image data (Y37). The duplication is continued until all image data are duplicated completely (Y38).

For example, if the directory configuration 4 d (including DPOF file and image data) shown in FIG. 33A is stored in the data server 4, the photo vending machine 5 (5 a) duplicates the directory configuration 5 bd as shown in FIG. 33A.

The photo vending machine 5 carries out image processing in accordance with the contents of the DPOF file after the duplication of the image data and the like is completed (Y39). Then, the photo vending machine 5 displays images to be printed (Y40). For example, the photo vending machine 5 carries out the image processing such as trimming, superimposing, and date imprint, and displays the images after the image processing.

In accordance with the user's instruction for printing, the photo vending machine 5 calculates fee (Y41) and waits for payment (Y42, Y43). If any cancel event occurs at Y43, the process flow returns to Y2.

After the payment, the photo vending machine 5 executes the printing (Y44).

The photo vending machine 5 instruct the data server 4 to delete the data, after the printing is completed (Y45). More precisely, deletion of DPOF file, image data, and directory is demanded.

The photo vending machine 5 disconnects from the data server 4 (Y46), and issues a receipt (Y47). Then the process flow returns to Y2.

The responding process carried out by the data server 4 which intermediates the data transfer between the photo vending machine 5 and the mobile phone 2 will now be described with reference to FIG. 36.

As shown in FIG. 36, the data server 4 initializes the system (YS-1), and waits for access (YS-2).

In response to access from the mobile phone 2 or the like, the data server 4 determines whether a directory is designated or not (YS-3). In case of no directory designation, the process flow skips to YS-7 (described later).

In a case where a directory is designated, the data server 4 recognizes the existence of the directory concerned (YS-4), and prepares the directory only if the designated directory has not existed (YS-5). The data server 4 indicates the directory concerned as current directory (YS-6).

The data server 4 determines whether the DPOF file from the mobile phone 2 has arrived or not (YS-7). Only when the DPOF file has arrived, the data server 4 stores it in the current directory (YS-8).

The data server 4 further determines whether the image data from the mobile phone 2 have arrived or not (YS-9). Only when the image data have arrived, the data server 4 stores them in the current directory (YS-10).

Then the data server 4 detects whether the mobile phone 2 is disconnected or not (YS-11). If the connection has been maintained, the process flow returns to YS-3. When the disconnection is detected, the process flow returns to YS-2.

According to the network printing system of the seventh embodiment, printing service for printing images captured by the mobile phone 2 with camera function is available with using the network. According to the seventh embodiment, the image data designated by the DPOF file of the mobile phone 2 are automatically transferred to the photo vending machine 5, thus the users are released from troublesome operations when using the system. Moreover, it does not require the user to bring the terminal device with him/her at the time of printing.

Though, the seventh embodiment above exemplifies a case where the image data are transferred to the photo vending machine 5 after those are transferred to the data server 4 once, the mobile phone 2 may transmits the image data and the like to the photo vending machine 5 directly.

Instead of the mobile phones 2 (2 a, 2 b, and 2 c), the PC 2 d or the PDA having camera function is also applicable one as the terminal device 2. Moreover, a wrist watch having camera function is also applicable. In this case, even if Java application software which realizes the above described image data transmission process is installed in the wrist watch, it works as the terminal device 2 as well as the mobile phone 2 exemplified in the seventh embodiment. Those Java application software may be downloadable from, for example, the network server 3.

Through the fourth to seventh embodiments, the photo vending machine 5 obtains e-mail address of the mobile phone 2 itself. However, the photo vending machine 5 may obtain user ID or nickname from the user, and asks the data center (data server) 4 or the like the e-mail address of the mobile phone 2 with notifying the user ID or nickname.

In this case, the data center (data server) 4 may previously have account information including an address finder table 4 t as shown in FIG. 37. The address finder table 4 t records relational information for introducing e-mail address based on user ID, nickname, phone number, manufacturing No. (serial No.) of the mobile phone 2, and the like.

When a user inputs any one of nickname, phone No. and serial No. on the photo vending machine 5, the data center (data server) 4 refers the address finder table 4 t, and informs the photo vending machine 5 of the e-mail address of the user's mobile phone 2.

The e-mail address information or the like may be supplied to the photo vending machine 5 during the data transfer between the mobile phone 2 and the photo vending machine 5. For example, the mobile phone 2 displays predetermined QR code (2 dimensional code) to be presented to the photo vending machine 5. That is, the photo vending machine 5 may scan the QR code displayed on the mobile phone 2 to obtain the e-mail address information. Instead of the QR code, predetermined color code may be applicable. Or, the mobile phone 2 may display text information representing the e-mail address, and the photo vending machine 5 may carry out character recognition to obtain the e-mail address.

Any communications method such as infrared or wireless communications (wireless LAN, Bluetooth, or the like) may be applicable for transferring data from the mobile phone 2 to the photo vending machine 5.

According to the above description, the present invention realizes printing service for printing images captured by any terminal device, via the network.

Moreover, more useful and interest photo prints are available by the present invention.

Various embodiments and changes may be made thereunto without departing from the broad spirit and scope of the invention. The above-described embodiments are intended to illustrate the present invention, not to limit the scope of the present invention. The scope of the present invention is shown by the attached claims rather than the embodiments.
